The FAT12 File Truncation Bug (brutman.com)
A few weeks ago I was doing some research on the FAT12 and FAT16 filesystems in an attempt to improve my NetDrive code, and I found a bug that can lead to a perfectly valid file being truncated when you move from DOS 2.x to later versions of DOS.

RealDOOM: Doom Ported to 16-bit Real Mode (github.com/sqpat)
RealDOOM is an in progress port of the DOS version of DOOM (based on PCDOOMv2) to Real Mode to support 16-bit processors (namely the 8088 and 286). It is meant to be accurate to the original game and id software WADs first and foremost. So it should work with timedemos, and have the support for the same level of graphical detail as the original game.
